• What is the cause and solution for SAP error message /SMB/FKCHK028 - Field of table and filed of value table have different domain ?

  The SAP error message /SMB/FKCHK028 indicates that there is a mismatch between the field in a table and the corresponding field in its value table regarding their domains. This typically occurs during data entry or when trying to save data in a transaction that involves a field that is supposed to reference a value table.
  Cause:
  
  Domain Mismatch: The field in the main table and the field in the value table are defined with different domains. A domain in SAP defines the technical attributes of a field, such as data type, length, and value range.
  Incorrect Configuration: There may be a configuration issue where the field in the main table is not correctly linked to the appropriate value table.
  Data Type Issues: The data types of the fields may not match, leading to this error when the system tries to validate the data.
  
  Solution:
  
  
  Check Domain Definitions: Verify the domain definitions for both the field in the main table and the field in the value table. Ensure that they are consistent in terms of data type and length.
  
  Use transaction code SE11 (Data Dictionary) to check the domains.
  
  
  
  Adjust Field Configuration: If the domains are indeed different and should be the same, you may need to adjust the field configuration in the relevant table or value table.
  
  This may involve changing the domain of one of the fields to match the other or creating a new domain that both can reference.
  
  
  
  Data Validation: Ensure that the data being entered adheres to the expected format and values defined by the domain. If the data does not conform, it may lead to this error.
  
  
  Consult Documentation: Review any relevant documentation or configuration guides for the specific module or functionality you are working with to ensure that the setup is correct.
  
  
  Testing: After making changes, test the transaction again to see if the error persists.
